You get other things like mutual exclusion, a clean baseline regardless of whats in the main directory, and potentially in the near future a way to tie into lifecycle hooks for eg creation/deletion [1]. That last part is nice in the new agentic AI era where you might want to setup/teardown local services that are isolated to those directories. But yeah the filesystem cost is not ideal. I was just thinking about how to exclude my worktrees from timemachine backups automatically.
